SLOT AND SLUG'.

Specification of Letters Patent.

Fatented July 4:, 1916.

Application filed September 17, 1915. Serial no. 51,122.

To all whom it may concern:

Be it known that I, ALONZO E. RHODES, a citizen of the United States, residing at Hillel-est, in the county of New Castle and feit slugs, coins, or the like and prevent their passing through the slot, and second, to provide a slug having grooves or passageways which will permit the slug to pass through its particular slot in any of the several positions that it can enter the unobstructed end of the slot. 1 attain these objects by means of the slot and slug illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of a preferred construction of my slug; Fig. 2 is a perspective view of the slug of Fig. 1 turned around to show that the rear face is a dupli- Gate of the front face; Fig. 8 is a plan view of a slot block having a slot with inwardly projecting members adapted to permit the slug of Figs. 1 and 2 to pass through to a suitable lock mechanism (not shown) Fig. 4 is I a front elevation of the slot block of Fig. 3;

Fig. 5 is a perspective view of the slot block of Figs. 3 and 4 and having a part broken away to more clearly show the inwardly projecting members; Figs. 6, 7 and 8 show some of the possible modifications of my slot and slug; Fig. 6 is a front elevation of a slug having cylindrical lugs for forming the grooves or passageways on the slug; Fig. 7 is a front elevation of a slug having more grooves or passageways than the slug of the two opposite faces so that either of the two opposite faces may be used for the front face and that any of the other faces may be used for the top, bottom or side faces thus permitting the slu to pass through the slot in any of eight different positions.

The slot S in the slot block B is large enough to freely receive the complete slug and thereby place it with half of its grooves or passageways G in a vertical position; these are the grooves or passageways that act to permit the slug to pass the inwardly projecting members T of the slot S, as more fully hereinafter described. The remaining grooves or passageways G, namely those in a horizontal position in the slot S, have nothing to do with the passing of the slug through the slot at this time; they are of use only when placed in a vertical position in the slot S, and are on the slug to make it impossible to place the slug in the slot S, so that it will not pass through.

About halfway down in the slot S and in the path of the before mentioned vertical grooves or passageways G are a number of inwardly projecting members T, preferably one for each vertical groove or passageway G of the slug, although the number may be less. These inwardly projecting members T register with the vertical grooves or passageways G and permit the slug to pass through the slot S. It is evident that any set of parallel grooves or passageways G may be used for passing the inwardly projecting members T, also that should a counterfeit slug, as one not having the proper grooves or passageways G, be inserted in the slot S, it. will descend in the slot until it meets the inwardly projecting members T when its passage through the slot is prevented.

I am aware that prior to my invention slots have been used to pass slugsto a lock mechanism. I do not claim such a combination broadly, but

I claim:

1. A slug consisting of a thin substan tially square central member with raised members or lugs arranged in rows for forming grooves or passageways at right angles to each other and substantially alike on two opposite sides of the said thin square central member, substantially as set forth.

2. A slug having grooves or passageways on two opposite faces and at right angles to other similar grooves or passageways on said faces, substantially as shown, for the purpose specified.

3. The slug M, having lugs L, arranged in rows for forming grooves or passageways G at right angles to each other and substantially alike on two opposite faces of the slug, substantially as shown, for the purpose specified.

4. A rectangular slot S, having inwardly ,projecting members T, each directly opposite a similar inwardly projecting member and with a space less than one half the width of the rectangular slot S between the inner surfaces of said members T, substantially as shown, for the purpose specified.

5. The combination, in a slot and slug, of a slot having members extending partially across the slot and opposite similar members extending partially across the said slot, with a slug having grooves or passageways at right angles to each other and substantially alike on two opposite faces of the slug, substantially as shown, for the purpose specified.

6. The combination, in a slot and slug, of a rectangular slot having members or lugs below the slug entering end and extending inwardly substantially one third the width of said rectangular slot, with a slug having four smooth faces and two faces with grooves or passageways parallel with the four smooth faces whereby any of the smooth faces may be used asthe bottom or entering face and either of the grooved faces may be used as the front face, substantially as described.

7 The combination, in a slot and slug, of

i a slot S, having members T, each extending partially across the slot and opposite a similar member, with a slug M, having lugs L, arranged in rows at right angles and alike on two opposite faces of slug M, sub- ?itantially as shown, for the purpose speci- 8. The combination, in a slot and slug, of a slot S, having members T, each extending into'the slot and directly opposite a similar member T, with a slug M, having lugs L, for forming grooves or passageways 6, across the slug in two directions, substantially as shown, for the purpose specified.

9. The combination, in a slot and slug, of a slot having inwardly projecting members extending approximately one third across the slot, with a slug having grooves or passageways at right angles to other similar grooves or passageways and substantially alike on two opposite faces of the slug, subfsitantially as shown, for the purpose speci- ALONZO E.
